How to Winterize Fire Protection Systems: A Facility Manager's Guide

As temperatures drop, freezing weather can put your facility's fire protection systems at risk. Frozen pipes, cracked valves, water damage, and equipment failures can lead to costly repairs and compromise critical life-safety systems.

Preparing your fire protection systems before winter arrives can help identify potential problems early, reduce the risk of weather-related damage, and keep your building protected throughout the season.

Fire Equipment Inc. (FEI) helps facilities maintain their fire protection systems through inspections, preventative maintenance, installation, and service, including 24/7 emergency support.

Whether you manage a commercial building, warehouse, industrial facility, healthcare property, or multifamily building, here's what to review before freezing temperatures arrive.

Why Winterizing Your Fire Protection Systems Matters

When water freezes inside a pipe, it expands. This can damage fire sprinkler pipes, valves, and other system components, potentially leading to leaks, flooding, and expensive repairs when temperatures rise.

Cold weather can also affect fire alarm equipment, backup batteries, and fire protection components located in unheated or damp areas. Heating failures, power outages, and severe weather can create additional challenges for building safety systems.

Proactive maintenance can help you identify vulnerabilities before winter weather leads to equipment damage or system impairment. Here are the key areas facility managers should prioritize.

1. Inspect Your Fire Sprinkler Systems

Fire sprinkler systems require special attention before freezing temperatures set in. Wet, dry, pre-action, and antifreeze systems each have specific inspection and maintenance requirements to help protect against cold-weather damage.

FEI recommends having fire sprinkler systems inspected and tested before the onset of cold weather. Key areas to review include:

• Fire Department Connection (FDC): Check for trapped water and confirm that ball drips and other applicable freeze-protection components are functioning properly.
• Pipe insulation: Inspect attics and other vulnerable areas to ensure insulation around wet sprinkler piping is intact and properly positioned.
• Dry and pre-action systems: Check for flooding or unwanted water accumulation that could create freezing hazards or interfere with system operation.
• Low-point drains: Ensure applicable drains on dry systems are properly maintained to help prevent trapped water from freezing.
• Air compressors: Verify proper operation, system pressure, and settings. Drain accumulated condensate as required by the equipment and system design.
• Antifreeze systems: Have a qualified professional verify that the solution meets applicable concentration requirements and arrange adjustments or replacement when necessary.

A professional inspection can help identify deficiencies before they lead to equipment damage, unexpected water releases, or system impairment.

Because fire sprinkler systems are critical life-safety equipment, inspections, testing, adjustments, and repairs should be performed by qualified professionals in accordance with applicable codes, standards, and manufacturer requirements.

2. Check Your Fire Alarm Systems and Monitoring

Fire alarm equipment can be affected by cold temperatures, moisture, aging batteries, and power disruptions. Before winter arrives, review the following:

• Temperature control: Ensure the area around the fire alarm control panel stays within the manufacturer's specified operating range and that heating equipment is functioning properly.
• Backup batteries: Check battery age, condition, and replacement requirements. Batteries approaching or exceeding three years old warrant attention, but replacement should follow manufacturer guidance and testing results.
• Moisture protection: Inspect panels, devices, and associated equipment for water intrusion, condensation, or exposure to rain and snow.
• Wiring and connections: Look for visible deterioration, cracked insulation, or corrosion.
• Trouble signals: Have recurring notifications and equipment issues evaluated promptly.
• Alarm monitoring: Confirm that your monitoring service is active and that staff know how to report system issues. Following severe weather or power outages, address monitoring or communication trouble signals without delay.

Routine inspections and prompt attention to deficiencies help support reliable fire alarm operation throughout the winter. Maintaining an active monitoring arrangement also helps ensure signals can be communicated to the appropriate response personnel.

3. Don't Overlook Suppression Systems and Fire Extinguishers

Fire sprinklers and alarms are essential, but they're not the only components of your facility's fire protection plan. Clean agent systems, other specialized suppression systems, and portable fire extinguishers also require regular attention.

Clean Agent and Special Hazard Suppression Systems

Facilities with server rooms, data centers, industrial equipment, commercial kitchens, and other specialized environments may rely on clean agent or other suppression systems to protect critical assets.

Use your seasonal maintenance review to confirm that required inspections and maintenance are up to date. Have qualified professionals address deficiencies and verify that equipment installed in temperature-sensitive areas remains within the manufacturer's specified operating range.

Portable Fire Extinguishers

Before winter arrives, make sure extinguishers are:

• Accessible, visible, and secured in their designated locations.
• Current on required inspections and maintenance.
• Suitable for the environmental conditions where they're installed.
• Free from obstructions caused by seasonal supplies, equipment, or changes to storage areas.

Snow removal equipment, winter supplies, and temporary storage arrangements can create unexpected obstructions. A quick review helps ensure extinguishers remain accessible and ready for use when needed.

4. Review Building Heating and Insulation

Your building's heating and insulation play an important role in protecting fire protection equipment from freezing conditions. Even properly maintained systems can be vulnerable when installed in spaces that become too cold.

Before winter, facility managers should:

• Confirm heating systems are working in areas containing fire protection equipment.
• Inspect insulation around vulnerable piping, particularly in attics and exterior wall cavities.
• Check for drafts or gaps that could expose sprinkler piping to freezing temperatures.
• Monitor temperatures in unheated or infrequently accessed spaces.
• Establish procedures for responding to heating failures, power outages, and extreme cold.

Pay particular attention to areas with overnight temperature setbacks or limited heating. Continue monitoring vulnerable spaces throughout the season, since conditions can change after the initial inspection.

5. Make Winter Readiness Part of Your Maintenance Plan

Winter preparation shouldn't end with a fall inspection. Temperature fluctuations, heating failures, and changes to building conditions can create new problems as the season progresses.

To maintain readiness:

• Schedule professional inspections before freezing temperatures arrive.
• Monitor vulnerable areas throughout the winter.
• Document deficiencies and ensure recommended repairs are completed.
• Make sure staff know how to report leaks, equipment issues, and system trouble signals.
• Follow applicable impairment procedures and notification requirements if a fire protection system must be taken out of service.

A consistent maintenance plan helps you address problems early, reduce avoidable repairs, and keep your facility's fire protection systems in service.
